MP20073DH-LF-Z

MP20073DH-LF-Z is a DDR memory termination regulator with the output voltage (VTT) and a buffered VTTREF outputs is a half of VREF. The VTT-LDO is a 2A sink/source tracking termination regulator. It is specifically designed for low-cost/low-external component count systems, where space is a premium. The MP20073 maintains a fast transient response only requiring 20µF (2x10µF) of ceramic output capacitance. The MP20073 supports Kelvin sensing functions. Typical applications include notebook DDR2/3 memory supply and termination voltage in ACPI compliant, active termination busses.

• VDDQ voltage range from 1.3V to 6V
• Up to 2A integrated sink/source linear regulator w/ VREF/2 divider reference for DDR termination
• Requires only 20µF ceramic output capacitance
• 3.3V drive voltage and thermal shutdown
• 1.3V input (VDDQ) helps reduce total power dissipation
• Integrated divider tracks VREF for VTT and VTTREF
• Kelvin sensing (VTTSEN), ±30mV accuracy for VTT and VTTREF
• Built-in soft-start, UVLO and OCL
• MSOP8E package
• Temperature range from -40°C to +85°C
